Crash when Exchanging voices
When editing a score imported from MIDI file, program repeatedly crashes when trying to exchange voices in a particular measures. Sometimes it can be worked around by copying the measure contents to another measure, editing there and then copying back.
Steps to reproduce: Open attached score, go to measure 6 and select it. Then select "Edit...Voices...Exchange Voice 1-2".
Result: Program immediately crashes and gives the following error message on the console:
no JACK server found
exchange voice 0 1, tick 7200-8640, measure 0x5a06840-0x5a08d10
WARNING: Child process terminated by signal 11
In fact, when editing this file the program crashes so frequently at random times (moving cursor, adding notes, deleting notes) and also refuses to delete notes or enter notes in certain voices, that this score sample should be an excellent "bug" exposer.
